Reserved Lanes

Reserved lanes are 25 kilometres of roads set aside for the exclusive use of buses, taxis and carpooling. Thanks to these lanes, the public transit service provided by the STO is easier and faster than ever!

The travel times for the approximately 62,000 daily riders rival the times of motorists, especially during peak periods in the direction of traffic or on the busiest roads.  

The Rapibus: a bus-only corridor

The existing 25 km of reserved bus lanes are about to increase with the opening of the Rapibus corridor on October 19. This corridor will consist of a bus-only roadway more than 12 km long linking Labrosse and Alexandre-Taché boulevards that also provides service to the downtown areas of the Hull sector and Ottawa. Read more.

Share the road with the STO, it's a question of safety for everyone!

Whether you walk, cycle or drive, learn more about the safety rules at intersections with the Rapibus corridor.

Identification of reserved lanes

On the pavement

Diamonds and broken double lines marked on the pavement indicate that the lane is reserved.

Road signs

Road signs are posted to indicate when a lane is reserved and the types of vehicles that may use it. Below are a few examples:

  • Reserved lane for buses, taxis and vehicles with 3 or more passengers
  • Reserved lane Monday to Friday from 6 a.m. to 9 a.m.
Panneau indiquant que la voie est réservée en tout temps aux autobus, aux taxis et aux automobilistes transportant un minimum de 3 passagers
  • Reserved lane for buses, taxis and vehicles with 3 or more passengers
  • Reserved lane at all times
Panneau indiquant une voie réservée aux autobus, aux taxis en tout temps
  • Reserved lane for buses and taxis
  • Reserved lane at all times
Panneau indiquant la fin de la voie réservée
  • End of the reserved lane

Priority traffic lights

A priority traffic light makes it easier for buses to merge into the traffic lane. It is represented by a vertical rectangular white light on a black background, integrated into the standard traffic lights. This light is activated a few seconds before the green light.

Priority traffic lights are installed at different strategic intersections where reserved lanes are located:

  • Gréber and Gappe, north- and southbound;
  • Gréber and Maloney, northbound;
  • Gréber and Savane, southbound;
  • Gréber and Jacques-Cartier, southbound;
  • Maisonneuve and Laurier, at the southbound entrance to the Portage Bridge;
  • Alexandre-Taché and Châteaubriand, eastbound;
  • Fournier and Lac-Leamy, northbound.

To ensure fluid service, the electronic traffic light controllers at each intersection along Gréber and Fournier are fitted with a priority system. This technology extends the time of the green light by a few seconds or shortens the time of the red light, thereby allowing the bus to pass safely.

Conditions for using reserved lanes

In a reserved lane, motorists may not:

  • Use the lane when not permitted;
  • Stop or park their vehicle;
  • Use the lane to pass;

Moreover, it is not advisable to travel by cycle or walk in the reserved lane. Cyclists who choose to ride on the roads and in reserved lanes must ride on the far right side of the lane.
